To increase the floor output for selected tubing size and length the flow needs to be increased.

That is our boiler primary loop tubing size. Pex or cross linked polyethylene tubing is used to transfer heat to the floor. When we plug the 180 000 btu h and the 1 25 tubing into bell gosset s system syzer for a 50 propylene glycol filled boiler we get 17 31 gpm flow.
